MM3Z7V5C

onsemi · Zener Diodes · SOD-323FL

MM3Z7V5C from onsemi, in a SOD-323FL. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ANODE passive Anode terminal of the Zener diode; the connection diagram identifies pin 1 as ANODE, and the device must stay within the absolute maximum ratings (PD 200 mW, IZM = PD/VZ).
2 CATHODE passive Cathode terminal of the Zener diode, marked by the band on the package (band denotes cathode); the connection diagram identifies pin 2 as CATHODE.
